No. Variety matters, and it’s especially important to get variety in vegetables.

Kids can be balky eaters, but, ideally, they should learn to enjoy a wide range of foods in order to get all the nutrients they need, said Jeanne Cox, a pediatric nutritionist at Johns Hopkins Hospital in Baltimore. Feeding kids green beans every night, for instance, means they are not getting other nutrients they need. “They need broccoli, carrots, the orange and yellow vegetables in addition to the dark green,” said Cox.
